I dont' think so. Swirlbuster is an abrasive polish (SFX-2) with essentially an acrylic-polymer glaze that seals and fills imperfections. CG AIO is more like, well, AIO in that it simply cleans and seals...no abrasives or filling ability. To me, SwirlBuster actually sounds more like CG EZ Creme Glaze, which is an acrylic sealant that fills imperfections (although it still has no abrasives).
SpoiledMan, have you used it by hand? If so, how were the results?
